Can he play PF? He has a winning pedigree, with not just a national title but the tournament's most outstanding player award. He showed some range by making 36.5% of his 3s in his most recent year, albeit in a small sample size (19/52). His FT% went up every year from 58% to a respectable 77%. He has an NBA ready body, tipping the scales at 245 pounds. By all accounts he's a solid worker and team guy.
He measured a respectable 6'7.25 w/o shoes with a 7'2.75'' wingspan and 9'0.50'' standing reach. Also, he has a 9.75'' hand size (eat your heart out, Jaylen!).
For some reference, Grant Williams weighed 240 lbs. and measured 6'5.75'' w/o shoes with a 6'9.75'' wingspan and 8'8.5'' standing reach (2019 combine).
If he can passably play PF, I'd be very happy with him at 35. Looking at his clips, he still moves like a big man as opposed to a modern PF, but at 35 overall I don't think you worry as much about him being a tweener.
